How to open Classic TAS project in TAS C?
Classic TAS project file (.TAS9) cannot be upgraded directly to TAS C project file (.TAS).
This is due to different technology platform being used for Classic TAS and TAS C.
However, there is a workaround. Classic TAS project can be imported to TRB C. The project will be converted into a TRB C project. From there, export the TRB C model file and import into TAS C.
Do note that this workaround will remove all the finishes in the original Classic TAS project.
